[Check_mk (english)] check_mk-df - Alert on Inode Warn and Crit

Howdy,

We had a file system that recently went from 50% to 100% of available inodes consumed over the period of a couple of months.

Check_MK didn’t generate any alerts regarding inode consumption and reported status OK during the entire timeframe. I can see the historical data in the graphs that it accurately tracked the consumption of
inodes over time, just didn’t alert.

Is there any way to get the check_mk-df check to alert for inode consumptions?

HI Mike,

Which version are you using? I recall in 1.2.4 ish I wrote my own plugin for inode usage. I am now on 1.2.8 with WATO and the filesystem check supports inode monitoring and thresholds.

Hi Mike,

Did you specify thresholds for inodes already?
There are no default thresholds for inode usage, so you will have to
create a rule for this.

Evy

Thanks Evy, that’s it. I hadn’t defined any thresholds for inodes.

Howdy Paul,

I’m currently on 1.2.7p2 but migrating to a new instance that is running the latest 1.2.8.

I think the issue is the result of not specifying thresholds as Evy mentioned.

Thanks,

Mike
